There are three things humans need to survive: safe food, air and water. Unfortunately, with all of the pollutants in the environment, more and more people are being exposed to unsafe drinking water. A study conducted by Harvard researchers found that substances called PFASs (poly- and perfluoroalkyl substances) are showing up in drinking water. PFASs are used in fabricating commercial and industrial products, as well as aqueous film-forming foams (used in fire fighter training). These toxic chemicals are produced at industrial sites, military and fire rescue training facilities, wastewater treatment plants and airports. Over six million people live close to such facilities and are at risk for exposure. PFASs have been linked to testicular and kidney cancers, obesity, and the disruption of hormones. Because of their small size, toxic chemicals can quickly accumulate in a child’s body. Adults, on the other hand, need to be exposed to higher levels of toxins or exposed for longer periods of time before getting sick. Harvard researchers recently studied over 500 children, aged 13 years. They tested the concentration levels of PFASs, as well as tetanus and diphtheria antibodies. Children exposed to higher PFAS levels had a 25 percent decrease in antibodies. The theory is that PFASs interfere with a child’s immune function and reduce the effectiveness of vaccines. The best option is to purchase and use a quality water filtration system in your home, and maintain and change your filters as recommended. Then, simply pack water with you wherever you go within a PBA-free container. If purchasing bottled water, ensure you safely recycle all your plastic water bottles.
